spider veins I am 24 years old , and I'm noticing veins behind my knees, and calves, and on some on my thighs, there not that visible to others, but I notice them. I work-out in the gym and sometimes the back of my knees really hurt the day after. I would really like to know what it is I can do to prevent more from coming? Also does vitamin E help? please help!
